We are all made of stars

Recent celestial events have turned my thoughts to the late (and great) Carl Sagan. (When my Honey-Matt was in high school, he wrote to Carl to ask for advice on what to study. Carl's letter is a treasured possession.) (He said 'Physics', of course.) This audio is great - but a bit long. So I'm going to give you a few days to work it in. Listen not only to Uncle Carl, but especially Phil Hennes and (after the musical interlude) Neil deGrasse Tyson. Science is grand!
